About the site

Cooma is 8km south of 'Mittagang Crossing' on the Murrumbidgee River from where Cooma draws its water.

What's going on:

We are in a farming area. During the summer months, the water quality changes dramatically. Habitat to the platypus, also used for fishing and swimming. Water is drawn from the river at this site to be purified for drinking water for the town of Cooma; population about 9000.

Monitoring the raw water quality and purifying the water for human consumption.
